OK, i had a gws eps300c with a gear "D" on it....i used an 11x8 prop and it worked fine, i just bought eps350c with a gear "C"....can i use the same prop? i think all its doing is spinning more rotations or somethin.....can somebody tell me? i bought alot of 1180 props i dont wana have to switch..

no no no! dont use an 11-8 on a 350c on "C" gearing! you will over amp the motor. even a 10-8 is too much on a 350c (i know from experience) a 9 inch prop should work nicely i think. with the lower gearing it takes more work from the motor to get the prop spinning. thats why bigger props wont work because they take more effort to spin from their larger mass. thats why smaller props will work better on lower gearing
